From c42d9f32443397aed2d37d37df161392e6a5862f Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Thu, 10 Jul 2008 11:16:36 -0700 Subject: x64, x2apic/intr-remap: fix the need for sequential array allocation of iommus Clean up the intel-iommu code related to deferred iommu flush logic. There is no need to allocate all the iommu's as a sequential array. This will be used later in the interrupt-remapping patch series to allocate iommu much early and individually for each device remapping hardware unit.
